14 Claims;

I Th is .invention relatesto devices adapted to be mounted on fingernails so that they overliethe enter surfaces thereof and the principal object oi;the invention is to provide a simply constructed device of this character thatcan be readily attached to the finger nail without the use of ce- .rnfentitiousmaterialand will firmly adhere to the fin er nail durin g usage. Another object of the invention istofprovidea device of the indicated -1 jtype thatlcan be readilyandeasily mounted on or removed frqmthe finger nail without injury the finger nail and which, when,in position ,the finger nail; will prevent injury to thetip portion of the latter] A further object of the innew is to provide a detachable finger nail deyic e hayinga covering portion which .will protectively overlie the outer surface of .the finger ail and may be colored or decorated to suit the .taste .of the user thereof. 1 24 Other objects and advantages as well as the lnovel details of construction of this invention will fibicom apparent after; a consideration of the descrip tion fliereinbelow set forth,taken in connecn .theaccon panying drawing in which E g lisa perspective viewof a hand showing the inannerin which the devices constructed in accordance-with.the! invention are mounted on th nger naiIs j FigKZ is a topjview of a finger hav ng (a device constructed according to one 30 embodiment of the invention mounted i Fig, 3 isanenlarged top'viewioi the device shown Figf2; Fig. 4 is a sideelevation of the device looking frorn'the rightjof Fig. 3; Fig.5 is a sectional viewtaken on the line 55 of Fig. 3; Fig. 6 is :5 atop view of a inodified form of the invention nd i 'fgn'lf isapla view showing the under side the evi e i t a me -r: A

r .f Referring, more particularly to the drawing wherein like reference characters designate corresponding parts throughout the severalviews, 'the numrallll designates generally a finger .oflthe hand fillustrated'having a natural finger nail ll,"the tip portion of which is shaped and extends beyond theoutel lldiof the finger I!) in su lm s 4 Mounted on the tip portion of thefinger nail "l l isadevice made in'accordance with the invention andgenerally' designated-by the numeral -42} Thedevice-l2 comprises an upper or covering -portion 13, adapted to overlie the outer surfaceof thetipportion 'ofthe finger nail H and :anmunderportion M, adapted to be positioned .under the tip portion. of thefinger'nail, the upper 1 m flowerportions l3 and {4, respectively, co-

operating tot detaohahlyi ol fihe de ic ses rel in place onthe tip of the finger nail without injnryto the latter, as will be hereinafter more fully explained.

' The covering portion it is formed substantially in the shape ofiac'reseent so as to conforxnl to k 5 the shape" of the tip portion of a finger nail. which has been manicured or shaped to the usual form; the inner endportion T5 of the covering I3 being curved so as to conform to the inner edge of the tip portionflo'f the finger nail and? the 10 outer end portion thereof having jconvrging edges l5 so as to provide'a relatively pointed end portion El, corresponding to the outer end of the tip portion of the finger nail H, the inner ends of the edge portions l5 meeting with thefends .15 of the inner edge portion l5 to form the inwardly extending portions l8. The body portion of the covering 13 is curved in transverse section in varying degree so asto snugly fit against the outer surface of the' tip portion of the nail. As

shown :more' clearly in Figs. 4 and 5 theconverging edges l6, and end' portion Hand'the inner en'd portions I8 all lie substantially in the same plane, the body portion of the coveringf l3 graduallycnrving' away from these portions of the plane and havingits greatest distance thereiron! at a point situated substantiallyfifidway'cin the inner, edge portion l5 thereof. Itvtill thijis be evidentfthat thecovering portion l3 'ofthe device is similar in form to the tip. portion of a finger nail'which'is sha'pe'dinthe usual manner and when the device is in position "on thefin'ger nail will snugly overlieand completely eov er' the tip portion thereof, the inwardly extendingportions'il8 preferably tapering off to thesides of the finger nails. In those cases where th'e tipof the finger nail is notpointed the end person, i? formed by the converging edges is willof coi rse be eliminated; the edges !B in that case forniiiig a con'ti'n uouslycurved Iedgel It is also within 40 the contemplation of the invention to have the covering l3 shaped-tojconform to the configurationpi the entire finger nail so that whenl the device is mounted on the naiLIthe c yenne portion will entirely cover the outer surface ofthe 4 5 finger nail.

The covering portion it maybe madeflof any material having 'suflicient rigidity so that the covering portion will maintain its shapefduring usage. .1 preferably makethe eoveringp 'rtion fi of metal such as tin, brass; silver, gold, etc; which has been out, stamped or otherwise 'forrn'edto the shape desired. The covering portion may. also be coated, as by paint or enamel, or have decorative work thereon or maybe used as a setting Q it is pushed away from the outer edge portions 86 of the covering B3. The outer edges 26 of the under portion I4 and the edges l6 of the coveringifi are soldered or otherwise securely fastened together. Thedegree of curvature of thebody portion of the under side I4 is slightly less than that of the covering it so that a crescent-shaped slit oropening is'provided within which the tip portion of the finger nail may be inserted. Due to the fact that'the spacing between the covering 13 and theunder side l4 gradually narrows down towards the outer edges of the device, as clearly shown in Figs. 4 and '5, it will be seen that when the device is pushed on the tip portion of the finger nail, the forward edge of the latter will wedge between the covering I3 and the underside it, whereby the device is securely held in position on the finger nail, As will benoted from Figs. 4 and 5 of the drawing, the underside M: is relatively thinner than the covering i3 sothat as the finger nail is-inserted in position in the device the under side 14 will tend to give without deforming the covering I3. The under side I4 is made of a material having sufiicient resiliency so that when the covering l3 by the inserted nail, it will be placedunder tension and bear tightly up against the under side of the tip portion of the finger nail; To obtain the desired spring or fastening result I preferably make the under side Moi relatively thin metallic material, although other materials may be used to equal advantage. It will'be thus seen from the above description that the device can bereadily and easily attached to or removedfrom the tip portion of the finger nail; and while mounted therei on will be securely held to the tip portion of the finger nail without any dan'ger of falling off during' usage.

In the embodime t in Figs; 6 and 7 of the drawing, the eovering portion 25 is provided with anintegral lnwardly extending flange 2B or), the under side thereof, which forms a support for the flexible under portion 29. This construction is assembled byslidably'inserting the under portion 29 in position, after which the flange 28 may be crimped to securely and permanently hold the under portion 29 in place. In the modified construction illustrated in these figures, the covering 25 is provided with an inwardly extending portion 26 which extends over the outer surface of the finger nail. 'This extension tends to enablethe device to obtain a firmer grip onthe fingernail, thereby lessening the chances of its desirable decorative efifect; To enhance this decbeing knocked off during usage and also gives a orative 'efi'ect, precious or semi-preciouslstones 27 may beset in the covering portion and extension 26, as illustrated It is, of course, understood; that various other hanges, and modifications, may be made in the details of construction and design of the invention without departing from the, spirit thereof, hence I do'not wish to limit myself strictly 'to the specific constructionsabove described.
